What the respiratory system consists of.

Structure of respiratory system

Nasal and oral cavities

Breathing, swallowing and choking

Nasal lining

There are many mucous membranes in your nose and trachea. These moisten the air, filter the air and thus produce mucus. How do you notice this?

What is better: breathing through your nose or mouth?
